In this section we will take a look at how to use the TI 84 Plus to calculate the present and future values of uneven cash flow streams

3. Chi-Square table p-values: use choice 8: χ2cdf ( The p-values for the χ2-table are found in a similar manner as with the t- table. The calculator will expect χ2cdf (loweround, upperbound, df). a. Left-tailed test (H1: σ < some number) Let our test statistic be χ2 =9.34 with n = 27 so df = 26. The p-value would be the area to the left of the test statistic or to the left o In our case, we used matrix A. For Expected, this can be any empty matrix (the calculator will automatically produce the expected values for us). In our case, we'll leave this as matrix B. Then, highlight Calculate and press Enter. The following output will automatically display: Step 3: Interpret the results This tutorial shares several examples of how to use the invT() function to find T critical values on a TI-84 calculator. Example 1: T Critical Value for a Left-Tailed Test Question: Find the T critical value for a left-tailed test with a significance level of 0.05 and degrees of freedom = 11

The problem is that the TI 84 Plus has no way to specify an infinite number of periods for N. Calculating the present value of a perpetuity using a formula is easy enough: Just divide the payment per period by the interest rate per period. In our example, the payment is $1,000 per year and the interest rate is 9% annually Find the Expected Value of a Game Using the TI-84 CalculatorVisit my channel for more Probability and Statistics Tutorials 2)containing the expected frequencies. 6.Enter the degrees of freedom (df). 7.Highlight Calculate and hit enter. 8.It gives you the test statistic (˜2), the P-value for the test statistic (p), the degrees of freedom, and a list of contributions to the ˜2 test statistic (CNTRB). This is the list of (O i E i) 2 E i values that you sum to get.

For Expected, choose list L2. For df (degrees of freedom), enter # categories - 1. In our case, we have 5-1 = 4. Then highlight Calculate and press Enter. The following output will automatically appear: Step 3: Interpret the results. The X 2 test statistic for the test is 4.36 and the corresponding p-value is 0.3595. Since this p-value is not. High-resolution, full-color backlit display and built-in MathPrint™ feature, the TI-84 Plus CE graphing calculator makes comprehension of math and science topics quicker and easier. Includes a TI Rechargeable Battery. Ideal for middle school through college Fortunately, the TI 83 Plus and TI 84 Plus have the TVM Solver, which can do the calculation quite easily. Technically, you could also use the IRR function, but there is no need to do that when the TVM Solver is easier and will give the same answer. To calculate the YTM, go to the Finance menu and bring up the TVM Solver Here, we use a TI-84 Plus to calculate Net Present Value (NPV). The process should be the same for a TI-84, TI-83, and TI-83 Plus c) Set the WINDOW at Xmin = -1, Ymin=-1, Ymax= the largest value of b plus a few units, say 5 in this problem. The value for Xmax is a bit more difficult to anticipate. If there is an equality with a negative slope, I usually make Xmax = 4/3*b/m, round it off to the next largest whole number and add a few units

Step 3: Find the variance. Your TI-83 or TI-84 doesn't find the variance for you automatically, but since the standard deviation is the square root of the variance, you can find the variance by squaring the standard deviation. It would be wrong to compute s² = 3.17² = 10.05 — see the Big No-no for the reason. You could enter 3.165257832².

To calculate the z-score in a TI-84 calculator, we would simply type in the following formula: This tells us that an individual value of 14 has a z-score of 1.4286. In other words, the value 14 lies 1.4286 standard deviations above the mean. How to Calculate the Z-Score of Several Values. Suppose instead that we have a list of data values and. 6 Finding areas under the Z (standard normal) curve Comment: These calculators give you the area between two values of Z. Example: Find the area between zero and 1.52. 1. Press 2ND and the DISTR key (DISTR is an abbreviation of the word distribution). 2. Press the down arrow until you get to the 2nd one. It is called normalcdf( If you want to substitute a value in a function, you could accomplish this task by using paper and a pencil. However, wouldn't it be easier to use your on your TI-84 Plus calculator to find the value of a function? There are a few different ways to accomplish this task. The TI-84 Plus C [ Enter L2 for Observed and L3 for Expected. For degrees of freedom df enter number of categories minus 1. In this problem, that's 4−1 = 3. Select Calculate and read off the results: the χ² test statistic is 2.45 and the p-value is 0.4838. p > α; fail to reject H 0

The Calculate option is the one you should choose i The TI-84 Plus is a fairly easy, but more difficult than most, to use financial calculator which will serve you well in all finance courses. This tutorial will demonstrate how to use the financial functions to handle time value of money problems and make financial math easy Notes: • With each rand execution, the TI-84 Plus CE generates the same random- number sequence for a given seed value. The TI-84 Plus CE factory-set seed value for rand is 0. To generate a different random-number sequence, store any nonzero seed value to rand

Step 2: Calculate the p-value using your calculator and the correct test. A t-test is used here since we have a big enough sample, and the population standard deviation is unknown. (We only have the standard deviation from the sample: .) Note that if we knew the population standard deviation, we would use a z-test instead. 1 Calculator Instructions for Statistics Using the TI-83, TI-83 plus, or TI-84 I.
